sTovE ATTACHMENT.

To all whom t may Concern.'

Be it known that I, JoriN A. BERRYMAN, a citizen of the United States,residing at New York, in the county and State of New York, have inventeda new and useful Improvement in StoveAttachments, of which the followingis a specification. y

This inventionvrelates to attachments for stoves, and has for its objectto provide for utilizing as far as possible all theheat generated from astove burner.

it is the special aim of the invention to provide an Vimproved cover forgas or other stoves which enables the heat generated by a single burnerto be utilized for heating two cooking vessels or-other articles andfurnishing hot water for domestic use, whereby it is possible to performwith one burner the same service and attain the same results as are nowordinarily obtained by the combined use of two burners of a gasstove andone burner of a gas water heater. Another object is to as evenly askpossible'distribute the heatV units generated from vthe single 5 burnerbetween the two cooking vessels or other articles to be heated. Y

The invention will be lirst hereinafter de-,

rFigure 1 is a plan View ofan attachment or cover for gas stoves madesubstantially inl accordance with this invention.

The attachment comprises a flue box havv ing a top plate .11,fafbottomplate 2 Spad below the same, and inclosing walls 3 extending between thetop and bottom plates all Speccation of Letters Patent.

bottom plate has an opening' 6 in vertical Y alinement with each oftheopenings' '4 in the; top plate; but has' no -Qpenings corre# spon'dingtothe openings V5 insaid top'plate. It y will be understood that theattachment isplaced on top of an ordinary gas stove so thatlthe openingsG will ybe directly over andabove two of theburners (not shown).Incline'd plates 7 extend from adjacent the margins ofthe openings inthe' bottom plate torrthe farther margins of the openings inthe topplate, and lserve to ydirect some of theheat units tothe openings L5.` Avertical partition 8 Vdivides the inclosure inthe at tachment into twocompartments', each in-e cluding one eachofthe openings 4, 5 and and oneof the inclined plates t7. The yprovisionof .this partition makes itpossible-to use oneburner only without allowing any of the heat units tobedstributed to Vmore thanv one of the openings Ztendone of the openings5.

The top plate is chambered as. at 9, around the openings 4f land 5 andthrough said` chamberedportion water is circulated for the purpose ofheating the same. A coil or pipe l0 mayl also be arranged overone ormore of the openings@ in the lOOttOm rplate.

2 so as-to vbe Y.directly lin the flame from the burner, Cold water froma boilery or tank, t not shown) is supplied'to the coil 10 and thelchambered portion of the top plate byfa pipe 11, Figs. 2 and 6, abranch pipelj2, Fig. 5, leading from the pipe l1 .t0 the @oily andanotherbranch pipe l5 leading from said pipe 11 -to the chamber -9After. cir;` cnlating through said `coil and chamber, the

hot water returns tok the boiler or tank through branch pipes ,13 `andllleadino respectively from the .chamber ,Sigand the "coily 1.0, and apipe 14 connected to said, .branch pipes, Figs.y 2, and 6,. y

Toiinsure ,the proper distribution iop-,tothe heat Y units vbetween eachIpair .of .openings Mld 5 the *10P Plateasteam generatorend ejector .18,is placed above ,each off ,the:ripen-` ng's ,Gfn the bottoni plate-so.as to .be d1# vrectly in the flame. As illustrated in Fig. 3,

.of the steaingeneratorsand eieetoizs-l comprises a long tubular body towhich water is fed from the pipe l1 via a branch Pill@ 17, Figs. 2 and6, and a small tube 21V connected to a. partition 22 in the outcrend ofthe body. The iiow of the water to the body of the generator, which isdirectly lin the flame, is controlled by a needle valve 19 having itsLtapered end 24 cooperating with` the flame. Y The small elongated tube2l pre-` vents the water being supplied in took large quantities andthesteam from forcing itself back into the water supply pipe 17. As'rast as the steam is generated, it is j ejected through the opening 20into the flame, thereby greatly improving combustion and blowing part ofthe heat units back to the open' ing 5 by reason of the fact that saidgen-- crator and ejector points rearwardly. The ejector in combinationwith the inclined plate '7 eiiectively distributes the heat unitsbetween the openings ,4 and 5, and make it;

possible for a singleburner to heat two cooking kvessels or otherarticles in addition to furnishing hot water by reason of the provisionof the chamber 9 in the top plate and the coil 10 inthe iiame.

Having thus described my invention what I claim as new and desire tosecure by Letters Patent is: v
